In Optimizely X, users are called collaborators. Collaborators have different levels of permissions. Use the collaborator roles to manage user-based permissions and access to your Optimizely X projects. These roles are especially useful when there are multiple people working on the same project or campaign.

The collaborator roles are:

Administrators have full access to all projects and account billing information. They can also add and remove other administrators. If you make someone an Administrator, they are one on every project. If you change an administrator to any other role, they lose all privileges on other projects.

Project Owners can create, edit, publish, start, and pause experiments and campaigns. A project can have more than one project owner. Project owners can also create new projects and invite editors and viewers to the projects they own.

Publishers can create, edit, publish, pause, and unpause experiments and campaigns; view results; and create and modify audiences, metrics, and pages. A Publisher has full power to create, start, and stop experiments, but cannot change the configuration settings for the project, e.g. the snippet.
